The turn signal buttons on our 2021 Model S Plaid yoke are very poorly designed. They are the same black color as the yoke and difficult to locate visually when the yoke is off center and your hands are not in the usual position, such as when you're trying to activate the turn signal while going around a curve. Also, stacking them one above the other on the left side increases the difficulty. Ferrari did a much better job in placing the turn signal buttons on their respective sides of the yoke: left turn button on the left side, right turn button on the right side.
Stalks are a very useful way to put certain controls within a finger's reach of the steering wheel while not cluttering the wheel itself with too many controls. Just because something's been around for a long time doesn't mean it's outdated. It is more likely a sign of its enduring utility.
One of the things I like about our Air over our Tesla is its less gimmicky control layout, with things such as A/C temp, fan speeds, air vent aiming, volume controls, and gear selection being accessible by means other than a central screen, or in addition to it.
